INVEN 70/? .4 TTOPNEY United States atent 3,015,981 ATTACHMENT COLLARS FER PAPER MILK CONTAINERS Richard H. Storer, Toronto, Ontario, Canada, assignor to Associated Advertising Limited, Toronto, Qatar-i0, Canada Filed Mar. 21, 1960, Ser. No. 16,318 1 Claim. (Cl. 40 -312) My invention relates to improvements in attachment collars and the like for use with containers. More particularly, the invention concerns an improved collar adapted to be secured on a standard pasteboard container of the kind widely used for the retailing of fluid sweet milk, buttermilk, and like comestibles.

Pasteboard containers of the class referred to are made in several sizes for holding /2 pints, pints and quarts of milk, etc., and in order to provide the different sizes it is usual to maintain the girth dimension of the containers and to vary the depth dimension thereof. In other words, the quart capacity would be twice that of the depth of the pint container. Such containers are fashioned with the well-known satchel top closure which includes oppositely disposed sloping walls meeting at a ridge strip formed by the pleated mouth section and the folded flaps that are stapled together in the closed condition of the container. The end wall-forming members of the top are folded inwardly beneath the said oppositely disposed sloping walls and one of these end wall members may be used to provide a pouring opening when the elements of the ridge strip are spread apart endwise.

In the retail dairy trade it is desirable to inform customers from time to time of things of interest, such as special sales of comestibles of which advantage may be taken, etc., and in order to achieve this a dairy will usually circularize its customers by notices placed on cards or other forms of circulars delivered with the milk or buttermilk. A more satisfactory and effective way of delivering such circular matters is to provide a printed collar devised for ready attachment to the containers and to afiix it to such containers so that the householders attention is directed to it in handling the same.

Hence it is the object of my invention to provide an advertising collar of the kind referred to which is selfattaching and one which securely aflixes itself to the satchel top of the container when placed thereon.

A further object of my invention is to provide a selfattaching collar comprising a fairly stiff disc of paper, pasteboard or the like slit in a manner to provide meeting tongues which flex to allow the collar to be placed on the ridge portion of the satchel top and which jointly grip this ridge portion and thus firmly attach the collar in place.

A still further object of the invention is to provide an attachment collar of the kind described which is inexpensive to manufacture and easy to apply.

With these and other objects in view the invention comprises the novel construction and arrangement of an attachment collar as disclosed in the ensuing specification and shown in the accompanying drawing forming a part of the same.

In the drawing:

FIG. 1 is a plan view of an attachment collar incorporating the invention;

FIG. 2 is a perspective view showing the manner in which the attachment collar is applied to the satchel top of a paper carton;

FIG. 3 is a fragmentary top plan view of the collar in applied position on the paper carton;

FIG. 4 is an edge view of the attachment collar in applied position and viewed at an end of the satchel top of the container.

In the drawing, the reference numeral 5 denotes the attachment collar as a whole which is a disc of stiff paper; i.e., paper of a thickness which is substantially formretaining although capable of flexing readily in a springy manner. The collar is desirably rectangular in shape but could be of other shapes according to requirements of use. A face of the collar is imprinted with a message (not shown) such as the advertising of a special common to the merchandising of the products of a dairy to which it is desired to bring to the direct attention of the householder.

The collar is slit transversely as at 6 intermediate of its width and thus forms two similar side sections 7 having ends 8 which are joined by the connecting sections 9 beyond the termini of the slit 6. Tongue elements 10 are formed in the plane of the collar by secondary slits 11 which divergently curve away from the termini of the slit 6 and thus convert the connecting sections 9 into detent elements, having inwardly directed points. Accordingly the collar is supplied with self-attaching means for attachment to a standard milk carton provided with a satchel top having recesses underlying opposite ends thereof.

The collar is placed on the standard carton denoted at 12, by pressing it downwardly on the satchel top 13 to cause the ridge strip 14 to project through the slit 6 with the tongues 10 flexed upwardly alongside of the ridge strip and lightly tensioned against the same and with one of the tongues engaged with the bottom edges of the flaps 15 which are stapled as at 16 in the sealing of the carton. The detent elements 9 are located at the ends of the ridge strip 14 and these detent elements are brought into locking engagement with said satchel top by pressing them downwardly so that their pointed detent portions are engaged under the oppositely disposed sloping side walls 17 (see FIG. 2). Said detent elements 9 thus positively secure the collar on the carton so that it cannot become detached inadvertently. The collar is applied with its printed side exposed so that it can be read by the householder when handling the carton at time of delivery. The collar can be readily lifted off the carton so that the latter may be opened.

From the foregoing, it will be understood that the invention provides an effective and reliable attachment device for a collar of the class described. Further, as dealt with earlier, the various sizes of the cartons have similar girth dimensions and therefore the collar will fit on the various-sized cartons.

What I claim is:

In combination, an advertising device, and a rectangular carton, said carton having a closure at one end, said closure having a transverse ridge strip and inwardly disposed side wall portions at opposite ends of said ridge strip, said closure including planar top portions diverging angularly from the base of said ridge strip and overlying said inwardly disposed side wall portions, said advertising device comprising a normally planar, foldable member including a linear slit shorter than said container ridge strip and terminating inwardly of opposite side margins of said foldable member, said foldable member including secondary slits extending from and communicating with opposite terminal ends of said linear slit, said secondary slits divergently and arcuately curving away from said terminal ends of said linear slit and terminating inwardly of said opposite side margins of said foldable member, said secondary slits forming inwardly projecting detent elements, said advertising device being disposed on said container with said ridge strip projecting through said linear slit, said linear slit defining opposite side sections on the planar, diverging top portions of said container,

said detent portions projecting into said inwardly disposed side portions of said container side wall portions, beneath the opposite ends of said ridge strip and normal to the general plane of said ridge strip.
